CULTIVATOR ATTACHMENT.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed October 24, 1906. Serial No. 340,373.

ments; the device, however, may be employed with equal advantage in connection with other kinds of apparatus.

The primary object of the invention is to provide an article of the nature set forth which is simple in construction and effective in action, and by which the beams of a cultivator or like implement can be easily and quickly separated or brought together to adapt the cultivator to the particular work being done. The attachment is what is known as a spreader.

In the drawings accompanying and forming a part of this specification I illustrate in detail one form of embodiment of the invention which to enable those skilled in the art to practice the same will be fully set forth in the following description while the novelty of said invention will be included in the claims. I

Figure 1 is an elevation of an attachment including my invention. Figs. 2 and 3 are detail views of the two legs of the said attachment separated from each other. Fig. 4 is an edge view of the operating lever and its attachments.

Like characters refer to like parts throughout the several views.

The attachment includes in its construction two legs as 2 and 3 which are curved longitudinally so that when assembled they present an arch. The leg 2 is represented as equipped at its upper end with a vertical neck 4 terminating at its upper end in a transverse head 5. The upper edge of this head is furnished with teeth as 6 arranged upon an arc, the center of which is shown as the pivot 7. This pivot joints the two legs 2 and 3 and is shown as situated below the neck 4. The lower ends of the two curved legs are provided with some suitable means vfor connecting the attachment removably with the beams of a cultivator. I will hereinafter describe means for this purpose. The pivot 7 may be of any desirable character and in addition to serving as a suitable connection between the two legs 2 and 3 also constitutes a support for the operating lever 8 which is forked to straddle the two 0011- neoted levers and which is represented as provided with a spring operated detent as 9,

the lower end of which is normally held in engagement with the teeth 6 by the power of the spring of said detent, the latter being guided in its end'wise movements upon the lever 8 by a loop as 10 suitably connected with said lever.

The lever 8 is represented as supporting a.

small lever as 11 illustrated as being of substantially angular form and fulcrumed at one of its branches upon the main or operating lever 8, the detent 9 being represented as connected with said small lever 11 at the angle of the latter. The leg 3 is represented as provided below the pivot 7 with a downward 6X- tension 12, to which the main or operating lever 8 is connected. The connection between the leg 3 and the lever 8 is therefore at one side of the pivot between the two legs 2 and 3. In the present instance the connection between the lever and the leg 3 is below the pivot 7 and said connection may be of any desirable character, for example, a pivot one as 7. The fork of the lever S as previously indicated straddles the two connected legs 2 and 3 and this tends to prevent relative lateral motion of said legs, although the leg 3 can be freely moved toward or from the leg 2 for the purpose of adjusting the distance between the cultivator beams. The latter operation is accomplished by the manipulation of the main lever 8. To adjust the cultivator beams the detent 9 will be disengaged from the teeth 6 by the operation of the lever 11 following which the lever, 8 will be swung to move the leg 3 toward or from the companion leg 2 in order to regulate the space separating the beams of said cultivator. When the desired adjustment is obtained the lever 1.1 will be released so that the detent 9 can be forced into engagement with the teeth 6 by the power of its spring.

The segmental head 5 is illustrated as provided near its opposite ends with stops as 13 which operate to limit the swing of the lever 8 and thereby prevent the latter from being accidentally moved from its proper relation.

The legs 2 and 3 are shaped at their lower ends to engage the beams of'a cultivator (not shown) and to be held thereto by suitable fastenings as the bolts 14.

What I claim is:

1. An attachment of the class described comprising two legs pivoted together, one of the legs having a downward extension and the other an upwardly extending neck provided with a toothed segment, both legs having means for their attachment removably with the beams of a cultivator, and a lever supported by the pivot connecting legs and jointed to said downward extension, said lever having a detentfor engagement with the teeth of said segment.

2. An attachment of the class described comprising two legs pivoted together, one of the legs having a toothed segment at its upper end located above the upper end of the companion leg, and the companion l'eg having a downward extension below the pivot uniting said legs, a lever supported forrocking movement by the pivot uniting said legs andconnected with said downward extension below said pivot, and a detent carried by the .leverfor engaging the teeth of said segment.

3. An attachment oflthe class described comprising two legs pivoted together, one of which has a neck rising above the upper end of the companion leg, said neck being provided with a toothed segmental head, said companion leg being provided with a downward extension, a lever supported for rocking movement by the pivot uniting said sections and connected with said extension below said pivot, and a detent carried by the lever for engagin'g'the teeth of said segmental head.

In testimony whereof I have hereunto set niy hand in presence of two subscribing witnesses.
